ICD-10 Code H35.103 – Retinopathy of Prematurity, Unspecified, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.103 – Retinopathy of prematurity, unspecified, bilateral
What it is
This code identifies retinopathy of prematurity affecting both eyes when the stage or severity is not further specified. Use it for premature infants with bilateral retinal vascular disease documented as retinopathy of prematurity.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal retinal vascular development in a premature infant, often detected on screening eye examination by ophthalmology.
When to use this code
Use H35.103 when the record clearly states retinopathy of prematurity, bilateral, but does not document a more specific stage or laterality code. It is appropriate for screening follow-up notes, consults, or discharge summaries that confirm the diagnosis. If the provider documents a more specific stage, code that instead.
Do not use for
Do not use this code for unilateral retinopathy of prematurity or when the stage is documented more specifically. Also avoid it if the chart only mentions prematurity without confirmed retinopathy.
Coding tip
Check the ophthalmology note for laterality and stage before assigning the unspecified bilateral code.
